General information only
All content on this website, including every calculator, table, article and answer, is provided for general informational and educational purposes only. It is not tax, legal, accounting, investment or financial advice, and it must not be relied upon as such.
We are not a certified public accountant, an enrolled agent, a tax attorney, a payroll bureau or a registered financial adviser. Using this site creates no professional, fiduciary or advisory relationship of any kind. Your tax situation depends on facts we cannot see, and only a qualified professional who knows those facts can advise you.
The output is an estimate
The calculator computes your estimated annual tax liability and divides it across your pay periods. That is not the same arithmetic your employer performs. Employers use the percentage method tables in IRS Publication 15-T, which estimate liability from each individual payment. Your actual paystub will therefore usually differ by a small amount.
What is deliberately not modelled
We would rather tell you the gaps than let you discover them:
- Tax credits — the Child Tax Credit, Earned Income Tax Credit, education and dependent care credits are not applied.
- Itemised deductions — we always apply the standard deduction.
- Local and municipal income tax — except Maryland's county tax at the statewide average. New York City, Yonkers, Philadelphia, Detroit, Columbus, Ohio school districts and Indiana counties are not included.
- State disability and paid family leave contributions — California SDI, New Jersey SUI/SDI/FLI, New York PFL, Washington PFML and similar programmes.
- Supplemental wage withholding — bonuses and commissions are commonly withheld at a flat 22% federal rate.
- Self-employment tax, multi-state or part-year residency, reciprocity agreements between states, non-resident alien withholding, and any treaty position.
- Head-of-household state brackets, which are approximated using single-filer thresholds in most states.
Tax law changes
Rates, brackets, wage bases and deductions change every year, and legislatures sometimes amend them mid-year or retroactively. We update as quickly as we can and we publish the date of last verification on every page, but there may be a gap between a change taking effect and our reflecting it. Always confirm current figures with the IRS or your state revenue department before acting.
Third-party content
We link to external sources so you can verify our figures. We do not control those sites and are not responsible for their content or availability. Advertising displayed on this site is served by third parties; we do not endorse advertised products or services.
No liability
To the fullest extent permitted by law, we accept no liability for any loss or damage — including underpaid or overpaid tax, penalties, interest, or lost income — arising from reliance on anything published here. Your use of this site is entirely at your own risk. This is set out more fully in our terms of service.
Found something wrong?
We take accuracy seriously and we publish corrections. If a figure looks wrong, please report it with the state, filing status and income you used so we can reproduce it.
